Raystar Product Introduction – 0.91 inch OLED REX012832F

RAYSTAR REX012832F is a popular small OLED display which is made of 128×32 pixels, diagonal size 0.91 inch, it’s very suitable for wearable device. The REX012832F has the same mechanical dimension as REX012832D but having different pin assignment and supports different interface. REX012832F module is built in with SSD1306BZ controller IC; it supports I2C interface and having 14 pins FPC pintout. As to the REX012832D module is also built in with SSD1306BZ IC but it communicates via SPI interface and having 15 pins FPC pinout. The standard emitting colors for REX012832F are available in white, sky blue and yellow.

Fastron News XHBHV – A leaded axial inductor designed to operate at voltage levels up to 400V

xhbhv

In addition to FASTRON’s standard leaded axial inductors the specialist adds a new ‘high voltage’ leaded axial inductor to the company’s product portfolio. Utilizing a special winding wire and a new coating, the choke can operate at voltage levels up to 400V and can withstand higher peak-voltage. Using a ferrite core the XHBHV choke offers inductance values from 100µH to 6800µH, ± 5% tolerance, maximum DCR from 0.22Ω to 14.16Ω, and current ratings (I1) from 0.22A to 1.76A.

The XHBHV inductors are a supplement to the standard leaded axial inductors for designs which are directly connected to the power line. Major applications for the XHBHV series are suppression of transients as well as EMC filtering in electrical motors and in switching power supplies used in home appliances, industrial, lighting, and automotive applications.

BRUCKEWLL 8ETH06 8A 600V Fast Diode Benchmarking

Fast diodes are necessary components in power PFC control applications and AC to DC transfer loop. Traditionally, designs use glass passivated discrete components, that allow a Trr (the crucial parameter for such applications) of around 35ns maximum. Several years of research have led to Schottky diodes based on a planar design, allowing a Trr reduction down to under 30ns, which is ideal for high frequency applications. Bruckewell Semi has just released the 8ETH06, an 8A/ 600V Diode with an ultra-fast 18ns Trr, it uses special design techniques to optimize commutation speed while reducing die size and cost.

The chart below compares the performance of Bruckewell device with similar components available in the market.

Typical applications are: snubbers in PFC of SMPS converters, inverters, induction cooking, DC motor control, freewheeling and polarity protection components.
